Asus has announced four new AM4 motherboards designed to support the new CPUs.
The ROG Crosshair VI Hero will be Asus’s AM4 flagship. It features superior cooling over the board’s power regulation circuitry, which should help to improve overclocking results. It also has a higher-quality audio sub-system that uses Asus’ SupremeFX technology to improve sound clarity.
Asus opted not to add display connections on the ROG Crosshair VI Hero. As this is a high-end board, video ports built into the motherboard since it is very likely they will never be used. All of the other new AM4 motherboards Asus announced do have video ports on board.
Next up is the Prime B350M-Plus, which uses the B350 chipset. Its feature set is further reduced compared to the X370 boards in that it has fewer power phases, smaller heatsinks, a less powerful NIC, and a lower-end audio chip. It also drops SLI support, as the CPU’s PCI-E 3.0 lanes are locked to a single PCI-E slot.
The last board announced, the Prime B350M-A, is also the only motherboard Asus announced today in the micro-ATX form factor. Although it technically can overclock too, it lacks heatsinks over the VRMs and will likely have poor overclocking results as a result.
All of these boards are now available for pre-order. See pricing information below.
